Gut Microbes May Hold Key to Colon Cancer Risk
10 Jun
Summary
- Gut bacteria in women with removed polyps resemble those in cancer patients.
- Specific microbes shifted in polyps group, mirroring cancer signatures.
- Healthy habits linked to better gut microbes and lower colon cancer risk.
A significant study in Cell Host & Microbe investigated the gut microbiomes of women years after they had adenomas removed. Researchers found that these women's gut bacteria differed measurably from those who never had polyps, showing similarities to microbial patterns associated with colorectal cancer.
The study identified 31 specific microbes that were consistently altered in both the polyp group and cancer patients. Elevated compounds tied to inflammation were noted, alongside reduced levels of a protective antioxidant. These microbial shifts were strongly linked to diet and lifestyle factors.
Encouragingly, the habits associated with a healthier gut microbiome in this study align with established advice for reducing colorectal cancer risk. Maintaining a diet rich in fiber, plant-forward foods, regular physical activity, and keeping up with recommended screenings are crucial for long-term colon health.
